Labels:text | screenshot | font OCR: EXPLANATION OF ENGINE AND PRESSURE-VOLUME DIAGRAMS: The purpose of these stacks is to illustrate the operation of several types of reciprocating engines (Gasoline, Diesel and Steam). In order to do this, and to emphasize the similarities as well as the differences between these engine types, an identical basic mechanism and cylinder pressure-volume diagram is used. It is important to observe some details closely in order to understand differences. For example, the compression ratio variations between different types is represented by differing distances between the piston at top dead center and the cylinder head. This clearance affects the shape of the pressure-volume diagram as the engine operates. Likewise, the timing of events has been carefully checked, in order to explain why certain ...
